Patent DE-2935410-A1 (DE)
Title: Indicator light for vehicle - has coloured reflector and inner window with array of lenses and outer cover with lenses and totally-reflecting prisms
Inventor: MARAHRENS FRIEDRICH
IPC: F21V9/08
Filed: 1979-09-01
Abstract: The indicator light has its colour produced by the colour of its reflector (10). The outer transparent cover (16) of the assembly has a gridwork comprising totally reflecting prisms (19) and lenses (18). An inner window (17) is located between the outer cover and the light-bulb and has lenses (20) to direct the light onto the lenses of the outer cover. External light incident on the totally-reflecting prisms (19) is reflected back outwards. The gridwork ensures that when the light is off, the colour of the indicator light is not visible. The outer cover may be replaced by a plane outer window with an extra window facing its inside surface. The extra window comprises a matrix of totally-reflecting prisms and holes. The holes take the place of the lenses in the original outer cover.

Title: External wall facing stone panel - has internal duct for solar heat conducting fluid, opening onto face
IPC: F28D1/047
Filed: 1979-09-17
Abstract: The panel-shaped unit is made of natural or artificial stone. It is mounted on the outside of a building wall to serve as a facing element. Inside the panel unit there is a duct (10) for a flowing heat-carrier, with both its ends opening out onto the outside surface of the panel. The duct can be in the form of a groove (3) worked into the panel surface, closed flush with it, containing a pipe and cavity filler or a flat rubber or sheet metal container, with filler in joints between panels. This can be incorporated in a solar energy system, without marring the appearance of the facade.
Patent DE-2937530-A1 (DE)
Inventor: GOLSER LEOPOLD DR
IPC: E04C1/41
Filed: 1979-09-17
Abstract: The invention takes as its departure point prefabricated structural elements which have at least one cavity (2) which is open at the top and bottom and runs parallel to a wall (1) to be arranged on the outer side. Structural elements of this type, whose cavities (2) are delimited wholly or partly on three or four sides and of which at least some have at least one opening (5) in the wall (1) to be arranged on the outer side, are joined together to form a masonry structure such that the structural elements provided with openings (5) are distributed uniformly over the outer wall of the masonry structure. During or after the erection of the masonry structure, the cavities (2) are filled, through the openings (5) and under an injection pressure of 2-6 bar, with a urea/formaldehyde resin foam having a density of 5-30 kg/m<3>. A largely cohesive insulating layer which exhibits virtually no cold bridges is thereby obtained in a cost-effective manner. <IMAGE>

Title: Monitoring and control of open=end spinning units - using control signals modified by feedback from individual units
Inventor: MIKULECKY KAREL DIPL ING
IPC: D01H13/32
Filed: 1979-11-02
Abstract: The production heads of textile machinery, such as open-end spinning units, are monitored and controlled by a device which receives response signals from each unit describing its performance and compares them with a programmed series of control signals. Differences between the two are used to effect adjustments to the individual units either directly, by means of mechanical adjustments, or indirectly, by means of corrections to the programmed control signals. The device has a rapid response, even with high-speed units, and maintains a high productivity of high quality output at every head, despite variations in operating characteristics of the individual heads.

The release is operated by inserting a flat object such as a flat plastic strip, or the handle of a spoon, into the gap between the edge of the door and the front of the machine, or into a suitably, situated aperture in the rim of the door. The device can be simply applied to either left or right-hand opening doors; it is safe from operation by accident or by children.
Patent DE-3009612-A1 (DE)
Title: Adsorptive extraction of hydrocarbon(s) from gas mixture - preceded by combusting gas addn. above inflammability limits
Inventor: WEYER HORST DIPL ING
IPC: B01D53/04
Filed: 1980-03-13
Abstract: Combustible components are removed by adsorption from gas mixtures, e.g. from hydrocarbon containing exhaust air from loading operations in mineral oil refineries. To remove any risk of an explosion, this treatment is preceded by inertising the gas mixture through the admixture of combustible gas. The admixture is controlled to achieve a total combustible gas concentration of at least 50% above the upper inflammability limit. This keeps the quantity of the waste gases to be treated to a minimum. An admixture of air to reduce the concentration 50% below the inflammability limit would amplify 1000 cu.m. to 50 000 cu.m., instead of 1300 cu.m. with the new method.

Patent DE-3032746-A1 (DE)
Title: Heat insulating pneumatic window curtain - has bellows unit filled with compressed air and released to fold together
Inventor: SCHATTA MARTIN
IPC: E06B9/24
Filed: 1980-08-30
Abstract: The pneumatic window curtain is esp. for reducing heat loss and cooling effect. A multi-track rail, is fastened inside between the two upright sides of the window opening, to accommodate a pressure-filled collapsible bellows-type unit in a cut-out. This receives filling pressure from manually or mechanically operated compressed air supply via a connected pressure pipe and three-way tap. Pressure release by the tap, in conjunction with internal draw belts, external clamping rings, and draw cables on front and rear stems, causes the bellows unit to fold together. The system adds effective heat and noise insulation to the normal screening functions of curtains.

IPC: H01F29/02
Filed: 1980-09-05
Abstract: The switching system for connecting the windings of a three-phase transformer into star or delta formation has a drive shaft (2) outside the switch-gear housing (10) controlling three switch sections (1). The drive shaft carries three right-angle drives (3) for three parallel shafts (4) each alongside a switch section. The continuous rotation is converted into a switching movement by a Maltese-cross mechanism (5) to operate the switch sections and the phase selector. In an alternative, the external drive shaft is connected by a right angle drive with a single shaft inside the housing connected to the first switch section and to the phase selector, with drive extensions for the other two switch sections. Another drive arrangement has only two switch sections.

Title: Locking ring forming machine - has bending roller between swinging jaws with cutters, towards which strip shaped blanks are advanced
Inventor: BURGER GEORG
IPC: B21D53/16
Filed: 1980-09-09
Abstract: The machine is for forming locking rings after they have been shaped by a cutter to form shallow V shaped members cut from strip material, using a bending mechanism towards which the strip is fed. Each member has an enlarged end with a hole through it and these ends are joined together. It is first bent round a shaping roller then inserted between spindles each with a clamping block at its end and sheared off between cutters. These are mounted on the ends of swinging clamping jaws attached at their other ends to a common hinge pin at the end of a reciprocating shaft. Each jaw has a semicircular cut-out forming a track for a spring loaded arm with a roller at its tip. This mechanism controls the action of the jaws which have a return spring between them and a roller around which they are bent further, to reach their final circular shape.

Title: Display and sales stand for newspapers or the like
Inventor: KOCH WOLFGANG
IPC: A47F7/14
Filed: 1981-01-07
Abstract: A display and sales stand for newspapers, magazines, records and the like has compartments which are arranged one above the other in the manner of a staircase and are bounded at the sides by side walls, a rear wall being arranged at the rear edge of each compartment shelf. In this case, the compartment shelves are inclined sloping down from the front to the rear, whereas their rear wall slopes up towards the rear at an angle to the floor. In this case, the rear wall of the lower compartment shelf forms the front wall of the next higher compartment shelf. A display and sales stand thus results, in which newspapers having inherently little stability can also readily be displayed and held, above all the newspaper title also remaining readily legible even if a compartment is not full of newspapers. The newspaper can namely be supported both on the compartment shelf and on the rear wall and, if appropriate, on the rear wall of the next lower compartment located in front of the compartment shelf. The visibility of the objects displayed is increased if a transparent material is used above all for the rear walls.
